Steps to reproduce:
- Go to http://<jenkins_url>/configfiles/.
- Click to "Add a new Config" and create a new one (for example a custom file with any content).
- Once submitted, go and edit it (change the content and click to "Submit").
- Open edit page again.
- The configuration content is the old one, the update did not have any effect.
- The configuration content is updated.
This was not happening in config-file-provider 2.15.3
